DIAGNOSTIC METHOD 1
Detect the malfunction by checking "Cumulative value of time when lambda changes from lean --> rich" in comparison to "Time during which diagnosis is in progress".
Scheme 162
- Abnormality Judgment
Judge as NG when the following conditions are established.
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| (Cumulative value of time when lambda changes from lean --> rich)/(Time during which diagnosis is in progress) | < 0.4 (Bin5 model) | P014C |
| < 0.38 (ULEV model) | P014E | |
| > 0.68 (Bin5 model) | P014D | |
| > 0.7 (ULEV model) | P014F |
JUDGMENT VALUE
Time Needed for Diagnosis: 90 seconds
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
- Normality Judgment
Judge as OK and clear the NG if the following conditions are established.
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| (Cumulative value of time when lambda changes from lean --> rich)/(Time during which diagnosis is in progress) | > or = 0.4 (Bin5 model) | P014C |
| > or = 0.38 (ULEV model) | P014E | |
| < or = 0.68 (Bin5 model) | P014D | |
| < or = 0.7 (ULEV model) | P014F |
JUDGMENT VALUE
Time Needed for Diagnosis: 90 seconds
